Adding a Disk Shelf to an Existing Storage Pool (BUI)
Before You Begin
■
For recommendations on how many drives to select per pool, as well as other considerations
and guidelines, see “Storage Pool Concepts” on page 109.
■
You must select the same data profile currently used in the existing pool. To understand the
different data profiles, see “Data Profiles for Storage Pools” on page 111.
■
If there is insufficient storage to configure the system for the data profile and its options,
some attributes may not be supported. For example, it is impossible to preserve NSPF
characteristics when adding a single disk shelf to a double parity RAID configuration with
the NSPF option. You can add the disk shelf, but cannot use the NSPF option.
■
Do not perform a pool configuration operation while a disk firmware upgrade is occurring.
To check if an upgrade is in progress, navigate to Maintenance > System.
Caution - Once a disk has been added to a pool, it cannot be removed without destroying the
pool entirely and losing all data.
1.
Install the new disk shelf using “Adding a New Disk Shelf” in Oracle ZFS Storage
Appliance Customer Service Manual.
2.
Go to Configuration > Storage.
3.
From the Available Pools list, select an online pool to which to add the disk
shelf.
4.
Click ADD.
5.
For this disk shelf, select the number of data drives for the storage pool.
If the new disk shelf does not appear, click ABORT, check the disk shelf cabling and power,
and begin this procedure again.
■
If all drives are the same size or rotational speed, or if one size is selected among multiple
sizes, the maximum number of drives available is allocated by default. If the storage device
contains drives of different rotational speeds or models, no drives are allocated by default.
■
It is strongly recommended that pools include only devices of the same size and rotational
speed to provide consistent performance characteristics.
■
Monitor or limit space usage because you may experience reduced performance when pools
approach full capacity.
6.
(Optional) Add any cache or log devices from the disk shelf to the pool.
7.
Click COMMIT.
8.
For data drives, select the same data profile used in the existing pool.
9.
If you allocated log or cache devices, select the appropriate profiles.
